Recommended separation distances between
portableandmobileRFcommunicationsequipmentandthe
models WL1 and WL3
The models WL1 and WL3 are intended for use in
electromagnetic environment in which radiated RF disturbances
is controlled. The customer or the user of the models WL1
and WL3 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile
RFcommunicationsequipment(transmitters)andthemodels
WL1 and WL3 as recommended below, according to the
maximumoutputpowerofthecommunicationsequipment.
